TRACTION-CARRIAGE.

SIEGIFICA'I-ION forming part of Letters Patent No. 726,897,. dated May5, 1903. Application filed February 25, 1903 Serial lie-145.076. (Nomodel.)

rovided, the lower ends of which are fastened to the bar D, and theirupper ends form bearings for the stub-shaft H, which is journaled alsoin the upright ortion 0 the axle, as shown in Fig. 2 of the drawin Toall whom it may concern: I Be it known that I, ISAAC S. FREEMAN, aUnited States, residing at Lyof Polk and tate of Wisd usefulImprovements in Traction-Carriages; and I do declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

form or box K, which has pivotalfconnection 'with the lower ends of thesupporting-bars N, N, and N saidbars N and N being pivotally mounted attheir upper ends upon t e stub-shafts 0, carried by the cross-bar D, andthe upper end of the bar N being pivotally mounted upon the axle, asshown in Fig. 2 of the drawings. Mounted upon said platform orreceptacle is a traction-engine Q, an if preferred, motor, eitherelectric type, may

for the purpose of he mechanism.

In the present case hown a traction-engine Q having ipes communicatingwith two engines,

having a swingin carry a traction engine or motor of any kind wherebypower may be imparted through suitable geared mechanism to thetractionwheels.

The invention consists, further, in various details of construction andin combinations and arrangements of parts,which will be hereinafterfully described and then specifically defined in the appended claim.

My invention is clearly illustrated in the accompanying drawings, which,with the letters of reference marked thereon, form apart of (indicatedby letters Q',) and each engine is connected with a driving-gear B, Fig.2 of the drawings. The gear B is fixed to a shaft R, which is journaledin the supports 1?, outer end of each shaft B has fixed thereto apinion-wheel J, which are in. gear wit the gear-wheel 0, whereby poweris communicated from the engines to the traction-wheels. Gear-wheels Iare provided,which are in mes with the wheels 0, two of which wheels Iare journaled on the stub-shafts O on each .side

Reference now being had to the details of the drawings by letter, Adesignates a dropaxle, the horizontal portions A of which formstub-shafts, on which the traction-wheels B are journaled. 'Saidtraction-wheels B may be of any suitable height, and their highestportions are preferably on line with the high- Fastened to eachgear-wheel C, which may be of any suitable d1ameter,'and D designates abar which is disposed at right angles to the upright portion of the axleA, as shown clearly in Fig. 1 of the drawings. ising from the end bars Dare the upright rods E, which are arched and supported by thestub-shafts O at the ends of the cross pieces or bars D, and suitablebraces G are of my invention it will be from the engines maytraction-wheel or the other for thepurpose of controlling the same, thepeculiar manner of suspending the carriage the latter is allowed to havea swinging motion, which, however, will enable the apparatus to be ingear in whatever position the platform orbox may be with reference tothe axle.

Having thus fully described my invention, what I claim as new, anddesire to secureby Letters Patent, is-- 7 A traction engine comprisingan arched axle, stub-shafts carried at the ends thereof,
